An 85 kg beam is fixed to a building at a pivot point (the origin) so the beam is completely horizontal. A cable runs from the building to the beam at a point located 2.5 m from the building and makes an angle of θ = 19.0 ◦ with respect to the building. The beam’s center of mass is 1.5 m away from the building. The beam maintains this horizontal position by applying a force directed into and down the building at the pivot point.

a. Draw the extended free body diagram for the beam (i. e. the beam and all forces on it).
b. What is the tension in the cable?
c. What are the x and y components of the force exerted by the building on the beam?

its c i just checked it

-4 on

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
